Soft Seated Gate Valve

A soft seated gate valve (often referred to as a resilient seated gate valve) is a multi-turn linear-motion isolation valve featuring a ductile iron wedge fully encapsulated in a synthetic elastomer (such as EPDM or NBR), engineered to close against a smooth, un-recessed interior body bore. The flexible elastomer wedge deforms slightly to absorb small pipeline debris and fill microscopic imperfections, achieving a 100% bubble-tight, zero-leakage seal with low operational torque. Conforming to standards like AWWA C509/C515, EN 1171, and BS 5163, these low-maintenance valves are standard specifications in municipal drinking water distribution, building fire protection mains, and wastewater collection, allowing civil contractors and water utility managers to prevent line leakage by importing certified soft seated gate valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
